Error code r1 Lo/Hi
Appliance Refrigerator
Quick answer

r1 Lo or r1 Hi marks a refrigerator compartment temperature sensor failure on Kenmore Trio bottom-freezer models starting 111.

Model compatibility

Kenmore reuses codes across series and model years, so r1 Lo/Hi may mean something different on another appliance or generation. Confirm this against your model’s documentation and record your full model number before acting.

Plain language

What this code means

The refrigerator compartment temperature sensor failed with a low or high reading.

On a Kenmore bottom-freezer Trio refrigerator with a model number starting 111, r1 Lo or r1 Hi means the refrigerator compartment temperature sensor has failed with a low or high reading. The manual adds that the codes reset after the failure is repaired.

What the manual says to do

  1. Unplug the refrigerator.
  2. Check the refrigerator temperature sensor wiring that runs to the control board for damage.
  3. Repair any broken wires.

What a technician checks

The next step is a resistance measurement through the sensor circuit from the control board. The sensor is replaced if the reading is not between 8,000 and 40,000 ohms.
